Japanese Utility Model Publication No. 6-24502 Japanese Utility Model Publication No. 3-20425 JP-A-10-131212

  The repair structure shown in FIG. 10A shows a method of covering the surface of asbestos slate roofing material 1 with waterproof paper 2 that can be fused. However, there is no description about the renovation structure of the eaves. For this reason, it was necessary to take measures to prevent asbestos (asbestos) dust from being scattered especially at the eaves where strength is required.

In the eaves member 6 shown in FIG. 10 (a), asbestos dust may be scattered from the gap between the falling edge 61 of the eaves member 6 and the existing drainer 5. In particular, the eaves of the asbestos slate roofing material 1 is large. In some cases, the gaps became even larger, causing breakage and cracks, and the possibility of asbestos dust scattering.
Moreover, the eaves-tip member 6 disclosed here is only for the case where the newly installed roofing material 3 is a horizontal roofing material.

  The eaves wrapper 7 in FIG. 11 is a metal plate bent in a substantially U-shaped cross section, and covers the eaves of the existing corrugated asbestos slate roofing material 1. However, since it is corrugated, there is a gap between the lower surface of the substantially U-shaped eaves wrap 7 and the rear surface of the peak portion of the corrugated asbestos slate roofing material 1, and asbestos dust may be scattered due to deterioration over time. was there. Moreover, even if the shape of the eaves wrap 7 is made to follow the shape of the corrugated asbestos slate roofing material 1, the new roofing material 3 is fixed by the fastening device 8 from the lower surface of the eaves wrapping 7 through the existing gutter attachment fitting. The back surface of the asbestos slate roofing material 1 at the location up to the main building where the house is located was still exposed, and there was a high possibility that the asbestos dust would be scattered due to damage.

The present application solves these problems, prevents the asbestos dust from scattering at the eaves, and prevents the asbestos dust from scattering between the existing drainer and the newly drained drain even when the asbestos slate roofing material is large. In addition, the present invention provides a repair structure that prevents asbestos dust from scattering from the back surface of the asbestos slate roofing material.
Furthermore, by using a combination of two members in order to prevent asbestos dust from being scattered, the purpose of not limiting the new roof material to be spread on the asbestos slate roof material is also achieved.

The present application uses an adhesive roofing, a covering reinforcing material, and a sealing material in a repaired structure in which a new roofing material is spread on an asbestos slate roof.
The adhesive roofing has an adhesive surface capable of adhering to asbestos slate roofing material on at least one side. Then, the surface of the asbestos slate roofing material is covered with the adhesive surface of the adhesive roofing.
The covering reinforcing material is composed of an existing draining covering material and an eaves covering material.
The existing draining covering material is at least a contact surface that can cover the back surface of the asbestos slate roof material that protrudes to the eaves side than the existing draining, and a folding that is obtained by lowering one edge of the contact surface. And a rising surface formed by raising the other edge of the contact surface.
The eaves covering material is at least a lower surface that can cover the eaves tip edge of the asbestos slate roofing material, an upper surface portion that is bent at the upper edge of the lower surface, and a lower edge of the lower surface that is bent in the same direction as the upper surface portion. And a coated surface.
Such an existing draining coating material and eaves coating material are attached, but the folded surface of the existing draining coating material is brought into close contact with the folded portion of the existing draining coating material, and the contact surface of the existing draining coating material is asbestos slate roof. Cover the back of the part that protrudes toward the eaves side of the existing drainer.
Next, the eaves covering material is combined with the existing drainage covering material. At this time, the existing drainage covering material and the eaves covering material are in close contact with each other through at least a sealing material placed inside the falling surface of the eaves covering material. Combine in this way.

According to the present application, since the surface of the asbestos slate roofing material is covered with the adhesive surface of the adhesive roofing, it is possible to prevent asbestos dust from scattering.
Moreover, in the eaves which require especially strength, since the asbestos slate roofing material is covered with the eaves covering material and the existing drainage covering material, stronger strength is obtained. By making the combination of the eaves edge covering material and the existing draining covering material according to the new roofing material, the shape of the new roofing material is not limited.
In addition, since the eaves covering material is combined with the existing draining covering material, and at least the sealing material is put inside the falling surface of the eaves covering material, the surface of the asbestos slate roofing material or the existing draining covering material and asbestos Asbestos dust can be prevented from scattering from between the slate roofing materials.
In addition, the folded surface of the existing draining coating is in close contact with the folded portion of the existing draining, and the back surface of the part protruding from the eaves side of the asbestos slate roofing material is covered with the contact surface and sealed. Therefore, it is possible to prevent the asbestos dust from scattering from the back of the asbestos slate roofing material.
Thus, the asbestos dust can be prevented from scattering.

The repair structure shown in FIG. 10A shows a method of covering the surface of asbestos slate roofing material with a waterproof paper that can be fused. However, there is no description about the renovation structure of the eaves. For this reason, it was necessary to take measures to prevent asbestos dust from being scattered especially at the eaves where strength is required.
According to the present application, not only the surface of the asbestos slate roofing material is covered with the adhesive surface of the adhesive roofing, but also in the eaves that particularly require strength, the asbestos dust is scattered using the covering reinforcing material and the sealing material. Can be prevented.
In the eaves member shown in FIG. 10 (a), there is a possibility that asbestos dust is scattered from the gap between the falling edge of the eaves member and the existing draining. Especially, when the eaves of the asbestos slate roofing material is large, The gaps became even larger, and breakage and cracks were more likely to occur, and the possibility of asbestos dust scattering was even greater. Further, the eaves member 6 disclosed in (a) is only for the case where the new roofing material 3 is a horizontal roofing material.
However, according to the present application, the surface of the asbestos slate roof material is covered with the adhesive surface of the adhesive roofing, and the eaves is covered with the covering reinforcing material. And asbestos is contained at least inside the falling surface of the eaves covering material of the covering reinforcing material so that asbestos dust is not scattered from between the covering reinforcing material and the asbestos slate roofing material. For this reason, strength can be maintained and asbestos dust can be prevented from scattering.
Furthermore, by using a combination of two members in order to prevent asbestos dust from being scattered, the purpose of not limiting the new roof material to be spread on the asbestos slate roof material is also achieved.

The eaves wrap shown in FIG. 11 is a metal plate bent into a substantially U-shaped cross section, and covers the eaves of an existing corrugated asbestos slate roofing material. However, since it is corrugated, there is a gap between the lower surface of the substantially U-shaped eaves wrap and the rear surface of the peak portion of the corrugated asbestos slate roofing material 1, and asbestos dust may be scattered due to deterioration over time. there were. Also, even if the shape of the eaves wrap is made to follow the shape of the corrugated asbestos slate roofing material, the asbestos from the lower surface of the eaves wrapping through the existing gutter mounting bracket to the main building where the new roofing material is fixed The back side of the slate roofing material remained exposed, and there was a high possibility that it would break and asbestos dust would scatter.
However, according to the present application, the surface of the asbestos slate roof material is covered with the adhesive surface of the adhesive roofing, and the eaves is covered with the covering reinforcing material. And asbestos is contained at least inside the falling surface of the eaves covering material so that the asbestos dust on the back surface of the covering reinforcing material and the asbestos slate roofing material is not scattered. For this reason, strength can be maintained and asbestos dust can be prevented from scattering.

An embodiment of the present application will be described with reference to FIGS. 1 and 2. FIG. 1 is an explanatory view showing a state where the asbestos slate roofing material 1 has been repaired using the covering reinforcing material A, the adhesive roofing B, and the sealing material C. FIG. 2 is an explanatory view of an embodiment of the covering reinforcing material A shown in FIG.
The asbestos slate roofing material 1 shown here is widely used in ordinary houses, and is a flat roofing material rather than a corrugated one. And it shows the eaves.

Next, the adhesive roofing B will be described. The adhesive roofing B is an adhesive surface B1 that can be adhered at least on one side. The adhesive surface B1 is stretched so as to be on the surface side of the existing asbestos slate roofing material 1 to prevent asbestos dust from scattering. . Of course, both surfaces may be adhesive surfaces B1.
Adhesion refers to those that melt and stick with heat, those that adhere with an adhesive layer with an adhesive, etc., and those that self-adhesive layer exerts adhesive strength over time and has the property of adhering to asbestos. Is.
And when metal members are used in the main building, corner building, keraba, etc., they are removed and left without peeling the asbestos slate roofing material 1, and the surface is covered with adhesive roofing B over almost the whole. cover.
By having the adhesive surface B1, even if a fastening device for fixing the newly-installed roofing material 3 to the field material 4 is driven, it is possible to prevent the asbestos dust from being scattered or leaking from there.

Further, referring to FIG. 1 and FIG. 2, an embodiment of the covering reinforcing material A used for the repair structure of the embodiment of the present application will be described. The covering reinforcing material A is made of a metal plate, and is composed of an eaves edge covering material A1 and an existing draining covering material A2.
The eaves edge covering material A1 of the present embodiment is a case where the newly installed roofing material 3 is a horizontal roofing material, and a locking portion A13 to which the eaves side of the newly installed roofing material 3 is fitted is formed. The lower surface A11 includes an upper surface portion A14 where the upper end edge of the lower surface A11 is bent, and a covering surface A12 where the lower end edge of the lower surface A11 is bent in the same direction as the upper surface portion A14. In some cases, the covering surface A12 is further folded inward. The locking portion A13 is bent and extended in the opposite direction to the upper surface portion A14 to form a flat surface portion A15, and the edge of the flat surface portion A15 is folded back to the upper surface side.

The existing draining coating material A2 of the present embodiment is composed of a contact surface A21, a folded surface A22 obtained by folding down one side edge of the contact surface A21, and a standing edge where the other side edge of the contact surface A21 is raised. It has a substantially Z shape having a raised surface A23, and the folded surface A22 is folded upward in the inner direction.
The existing asbestos slate roofing material 1 has slightly different protruding dimensions from the existing drainer 5 depending on the site. Also, even at one site, the eaves edge may be uneven. Furthermore, the design of the asbestos slate roofing material 1 may also have irregularities in the eaves tip edge rather than being substantially the same linear shape. In addition, there may be unevenness and the height above and below is not constant.
For this reason, when the existing draining coating material A2 is produced in the factory, it is preferable to make the length of the contact surface A21 longer and form the rising surface A23 at the site. Or you may manufacture the whole existing draining coating | covering material A2 on-site.

By forming the rising surface A23, the stiffness of the existing draining coating material A2 itself can be strengthened to prevent distortion. Moreover, before attaching the eaves tip covering material A1, when the existing draining covering material A2 is attached, the protrusion of the eaves tip edge and the height of the contact surface A21 can be made uniform.
Further, the rising surface A23 will be described in comparison with FIGS. The rising surface A23 is not formed on the existing draining coating material A2 in FIGS. This existing draining covering material A2 is manufactured by assuming a case where the eaves are large as shown in (a) in order to correspond to different eaves with one member. For this reason, when the eaves are relatively small, (b) is obtained. And when there is no starting surface A23, there are the following problems.
First, since the existing draining covering material A2 of about 3 to 6 is not provided with the rising surface A23, when the asbestos slate roofing material 1 is uneven, the contact surface A21 is also the asbestos slate roofing material 1. Wavy along the back of the. For this reason, when it is going to fit covering surface A12 of eaves edge covering material A1 according to the lower side of contact surface A21, eaves edge covering material A1 is very difficult to put. In particular, in a site where there is no scaffold, when the worker is directed from the roof to the eaves side and tries to fit the eaves covering material A1 from the roof, the construction is difficult.
However, the rising surface A23 is formed in the existing draining coating material A2 of the present application. For this reason, even if the asbestos slate roofing material 1 is uneven, the contact surface A21 and the rising surface A23 do not follow the unevenness and undulate. Therefore, when the eaves end covering material A1 is fitted, the eaves end covering material A1 may be applied to the positioned existing draining covering material A2, so that the construction can be easily performed. Even when a worker works from the roof to the eaves side at a site without a scaffold, it is easy to work.

Then, the Example of the sealing material C is demonstrated. The sealing material C shown in FIG. 1 is an elastic body having elasticity. As for the existing asbestos slate roofing material 1, the eaves from the existing drainer 5 is not constant. There may also be unevenness. For this reason, by using an elastic body, it is possible to cope with different eaves. The material and shape are not limited as long as it can prevent the asbestos dust from scattering.
In the case of the embodiment shown in FIG. 1, the sealing material C is pasted in advance in the factory in order to simplify field work. A band-shaped sealing material C is attached to the inside of the falling surface A11 and the coating surface A12 of the eaves-end coating material A1 so as to have a substantially L-shaped cross section. Instead of sticking one sealing material C so as to be substantially L-shaped, what is stuck on the falling surface A11 and the covering surface A12 may be divided. Furthermore, it is conceivable to use the sealing material C, which is an elastic body called a gasket, with a substantially L-shaped cross section, and the sealing material C may be applied on site.
The sealing material C of the present embodiment is attached to the falling surface A11 and the covering surface A12. The sealing material C only needs to be placed at least inside the falling surface A11. However, in order to further enhance the effect of preventing asbestos dust from being scattered, it is also affixed to the inside of the covering surface A12. In addition, this further restricts the movement of the eaves covering material A1 and the existing draining covering material A2, prevents rattling and increases the strength.
In addition, you may affix on the outer side of the starting surface A23 and contact surface A21 of the existing draining coating | covering material A2. You may affix on the outer side of starting surface A23.
If it is pasted only on the inner side of the covering surface A12, when the eaves covering material A1 is applied, it will hit the corners of the abutment surface A21 and the rising surface A23, and it is easy to turn over, and asbestos dust may be scattered. There is. Therefore, at least the sealing material C is interposed between the rising surface A23 and the falling surface A11 for sealing.

An embodiment of a repair structure using such a member will be described with reference to FIGS.
First, the contact surface A21 is brought into close contact with the back surface of the portion protruding from the existing drainer 5 toward the eaves side, the rising surface A23 is applied to the eaves tip edge of the asbestos slate roofing material 1, and the existing drainer 5 is covered. Cover the fold-down surface 51 with the fold-down portion 51, and stop with the fastener 8. The fastening tool 8 of the present embodiment stops the existing drainer 5 and the existing drainer covering material A2, and is driven into the field material 4 so that it cannot be seen from the lower side.
At this time, when there is a gap between the rising surface A23 and the eaves side edge of the asbestos slate roofing material 1, the gap may be filled with the sealing material C. However, since the sealing material C is put at least inside the falling surface A11, it is not necessary to put it.
Subsequently, the eaves covering material A1 is applied from the eaves side. At this time, the sealing surface C11 affixed to the inside of the falling surface A11 and the covering surface A12 of the eaves covering material A1 is used as the rising surface of the existing draining covering material A2. A23 is brought into contact with the contact surface A21 to seal between the eaves tip covering material A1 and the existing draining covering material A2. Then, the fastening device 8 is driven into the flat surface portion A15 of the eaves covering material A1 and fixed to the nose cover 9.
Furthermore, adhesive roofing B is stretched from above the flat portion A15 to cover the entire surface of the asbestos slate roofing material 1. In the case where the adhesive surface B1 has adhesiveness, the adhesive roofing B is heated and melted by solar heat and exhibits adhesive force, and adheres to the surface of asbestos. In the case where the adhesive surface B1 has an adhesive layer with an adhesive or the like, the adhesive roofing B adheres to the surface of asbestos by stretching the adhesive roofing B in order from the top of the flat portion A15 toward the ridge side. . As for the thing with a self-adhesion layer, adhesiveness increases with progress of time, and adhesive surface B1 closely_contact | adheres to the surface of asbestos slate roofing material 1. FIG.
The adhesive roofing B may be a paper impregnated with alphalt or a rubber-based material. The adhesive surface B1 is intended to adhere to asbestos and prevent dust from being scattered, so that at least one surface may be the adhesive surface B1. Although both sides of the adhesive surface B1 make it difficult for an operator to walk on it, depending on the shape of the new roof material 3, the back surface side of the new roof material 3 and the adhesive surface B1 may be brought into close contact with each other. it can.
If members made of metal plates are used in the main building, corner building, etc., they should be removed and only the asbestos slate roofing material 1 is applied, and then the adhesive roofing B is stretched. It is because it is better to remove the member which has less unevenness and is often rusted or damaged.
In this way, the portion where the asbestos is exposed is covered and the asbestos dust is prevented from scattering, and then the eaves side of the new roofing material 3 is combined with the eaves covering material A1.

Thus, according to the present embodiment, the asbestos slate roofing material 1 protruding from the existing drainer 5 toward the eaves is reinforced while covering the back surface and the eaves tip edge with the sealing material C and the covering reinforcing material A. For this reason, it is possible to prevent the eaves of the asbestos slate roofing material 1 from being damaged first.
Moreover, since the back surface and eaves edge of the asbestos slate roofing material 1 projecting from the existing drainer 5 toward the eaves are covered with the sealing material C and the covering reinforcing material A, the asbestos dust is prevented from scattering. be able to.
In the case of the present embodiment, first, the folded surface A22 of the existing draining covering material A2 is in close contact with the folded portion 51 of the existing draining section 5, and the eaves tip of the asbestos slate roofing material 1 with the existing draining covering material A2. The edge and the back surface of the portion protruding from the existing drainer 5 are covered.
And it has lower surface A11, upper surface part A14 which bent upper end edge of lower surface A11, and covering surface A12 which bent upper end edge of lower surface A11 in the same direction as upper surface part A14, and lower surface A11 and covering The eaves covering material A1 with the sealing material C applied to the surface A12 is combined with the existing draining coating material A2. Thereby, in the case of a present Example, the falling surface A11 and coating surface A12 of eaves-end coating | covering material A1, and the starting surface A23 and contact surface A21 of the existing draining coating material A2 are sealed. For this reason, the eaves point can be reinforced to prevent asbestos dust from scattering.

With reference to FIGS. 3A to 3C, another embodiment of the existing draining coating material A2 constituting the coating reinforcing material A used in the present application will be described.
(A) has a substantially Z-shaped cross section, and includes an abutment surface A21, a folded surface A22 obtained by folding one end edge of the abutment surface A21, and an upright end portion raised. It consists of surface A23.
In this way, the folding surface A22 is at least long enough to reach the folding part 51 of the existing drainer 5, and the fastening device 8 can be driven and brought into close contact therewith. It suffices to reach at least the forefront edge of the eaves tip edge of the asbestos slate roofing material 1 from the lower side.
(A) is a contact surface A21, a folded surface A22 where one side edge of the contact surface A21 is folded, a rising surface A23 where the other side edge is raised, and an upper end of the rising surface A23. It consists of a surface portion A24 whose edge is bent toward the contact surface A21. The length of the surface portion A24 may be such that the eaves tip edge of the asbestos slate roofing material 1 reaches the eaves tip edge farthest from the rising surface A23. The height of the rising surface A23 is preferably designed so that it can cope with some unevenness.
(C) shows a contact surface A21, a folded surface A22 where one side edge of the contact surface A21 is folded, a rising surface A23 where the other side edge is raised, and an upper end of the rising surface A23. It consists of a surface portion A24 whose edge is bent toward the contact surface A21. And the lower end edge of fold-down surface A22 in the case of a present Example is the length which covers the lower end edge of the existing draining, and it bends inward and hides the existing draining 5.

Further, another embodiment of the existing draining coating material A2 will be described with reference to FIGS. The existing draining coating material A2 in (a) is defined as an inner side surface A25 that is a side of the folded surface A22 of FIG. 3 (c) that is bent inward, and the upper end edge of the inner side surface A25 is bent outwardly to contact the field material. The surface is A26. The inner side surface A25 covers the inside of the existing drainer 5, and the field material contact surface A26 is a part that contacts the back surface side of the field material 4.
What is shown in (a) is the one without the field material contact surface A26 in (a).
Thus, various shapes of the existing draining coating material A2 can be considered. The asbestos slate roofing material 1 can cover the back surface of the portion protruding from the existing drainer 5, the contact surface A 21, the folded surface A 22 that is one end edge of the contact surface A 21, and the contact surface What is necessary is just to have the raising surface A23 which raised the other side edge of A21.

Next, the construction state when the eaves are different will be described with reference to FIGS. 5 and 6. FIG. 5 shows that the thickness of the sealing material C is relatively large, so that when the eaves of the asbestos slate roofing material 1 is different when the same eaves covering material A1 is used, the adhesion material C can be expanded and contracted. It shows that it can respond.
The diagrams (a) and (c) in the two circles at the bottom of FIG. 5 are arranged for easy comparison of the states. (A) is the principal part of FIG. 1, (c) is the principal part of FIG. 5 (a).
When the eaves from the existing drainer 5 is relatively large, the sealing material C shrinks as shown in (a), and when the eaves are small, it does not shrink as much as (c).

FIG. 6 shows that the eaves covering material A1 and the contact surface A21 of the existing draining covering material A2 overlap each other, corresponding to the difference in the eaves of the asbestos slate roofing material 1.
The diagrams (a) and (c) in the two circles below FIG. 6 are arranged for easy comparison of the states. (A) is the principal part of FIG. 1, (c) is the principal part of FIG. 6 (a).
When the eaves from the existing drainer 5 is large, the contact surface A21 and the covering surface A12 overlap shallowly as shown in (c), and when the eaves are small, the contact surface A21 as shown in (a). And the covering surface A12 overlap deeply.

FIGS. 8A and 8B show a sealing material C used when the existing asbestos slate roofing material 1 is a corrugated roofing material having a peak and a valley and having a small cross section.
(A) forms the peak part and the trough part also in the sealing material C according to the back surface side of the peak part and the trough part of the asbestos slate roofing material 1. And this sealing material C is affixed inside the contact surface A21 of the existing draining covering material A2, and during construction, from the back side of the asbestos slate roofing material 1 protruding from the existing draining 5 to the eaves side, Install according to the peak and valley.
(A) is a sealing material C having a rectangular cross section. The asbestos slate roofing material 1 is not adapted to the shape of the back side of the peaks and valleys, but even if it is such a shape, if the sealing material C is an elastic body, it will be crushed and existing draining coating material The space between A2 and asbestos slate roofing material 1 is sealed.

Another embodiment of the new roofing material 3 will be described with reference to FIGS. (A) shows a case where the newly installed roofing material 3 is a vertical roofing material, and (A) shows a case where the new roofing material 3 is a metal tile.
The shape of the eaves covering material A1 of the covering reinforcing material A is different from that shown in FIG. 1, indicating that the design can be changed according to the shape of the new roofing material 3.
In this way, in the present application, when the existing asbestos slate roofing material 1 is repaired, the folded surface A22 of the existing draining coating material A2 is brought into close contact with the folded portion 51 of the existing draining material 5. Then, the eaves covering material A1 and the existing draining covering material A2 are combined at the eaves, and further, the sealing material C is interposed at least inside the falling surface A11 of the eaves covering A1 to cover and reinforce the asbestos slate roofing material 1. And seal the asbestos. Therefore, the new roofing material 3 is not limited.

  Although the description so far has been the explanation about the eaves in the renovation of the existing asbestos slate roofing material 1, it can be similarly applied to the keraba by combining the covering reinforcing material and the sealing material.
